Robox DVR & Cam

[Bullseye 0]

Hi Everyone,

 

New to the site and cctv,

I have had 2 previous DVR's that needed a return due to poor quality, i just wasnt happy with them, I now have a Robox HD 8 channle 1080p DVR first impression Great!

 

2 Cams are down and im stuck with just the 1 (new covert cams to be ordered) I have a sony effio E 700tvl and basic all in 1 cables (RG59 to be ordered with compression BNC)

 

Now for my questions im confused as my picture quality isnt great, it started off ok but still not 100% happy, i thought/sure its just down to the cables

 

I havent bothered with the DVR for over a week now, on my return to see some footage the playback picture quality has got slightly worse, for example the faces look water painted on movement and pause if you know what i mean? picture very grainy and is worse when i put the resolution to 1080p, It was grainy anyway but not quite as bad, its not got crisp edges etc

 

I really do need quality, I know its just an entry level DVR £400 but im sure it should still give a much better picture

 

Would the simple fact its an all in 1 cable have this much effect on the picture quality? i know it would have some

 

Im about to spend another £200 on cable and a few cams but i cant have this quality i have now its no good,

 

Any info/help would be much appreciated!

Whats the record resolution on the DVR?

 

watery / washed out images are normally due to poor camera or settings

 

What is the image resolution set at?

Hi, thanks for the reply

 

Its D1 on all 8 channel 25fps

 

I set all the DVR settings to max, D1, 25fps, I put the Bit rate type from CBR to VBR and set it to 6 (max) Bit rate (kb/S) 4096

 

Im sure i havent touched the cams OSD menue however today i set it back to factory settings

 

I did notice this morning the recording wasnt watery and washed out but the picture still isnt crisp (maybe im expecting too much?)

 

After giving my settings what do you think it could be? would the cables have that much effect, is the DVR not up to standard? As i say the cam is 700tvl sony effio E, i need covert cams, can anyone point me in the right direction for tiny ccd 700tvl pinhole cams?

 

Picture quality really isnt what iwas expecting from this, i dont want to waste my money in buying the wrong products as i need to capture faces covertly, i know possitioning is key etc and i will do my best to get that correct but need the right gear at a fair price, from what im getting now isnt good enough, i thought i had all the settings correct etc from what i can see it could be the cables but if it isnt that perhaps the DVR? the cam has ok spec i think

 

Any advice etc would be much appreciated

Hi. The cheap type cables you get with kits r the DIY plug and play cables will give some problems but not much.

 

 

You are using a dahua DVR. (Rebranded).

 

You could for a test either replace cables for rg59 or with the cables you have buy 2 baluns and see if image is better....

Also with the dahua you need a wide screen monitor

Hi,

 

may i ask, what will the baluns do? reason i thought cables may be a slight problem would be as the power runs down the same cable and there quite thin, interference?

 

yes i noticed its a rebranded DVR, i notice they have some ok rep? Its a new model 1080p, has two ports for HDD with D1 on every channel, spec seems ok.

 

Its just hunting my problem of quality, i notice in shops etc they have crisp clear pictures and mine is nothing of the kind, dotty etc

 

Atm its linked to our 42" 1080p tv (will be getting a 22" soon) i realise that 42" is too big and would have some picture quality loss? i have tried it on a smaller basic square monitor but still notice the same problem

Am i able to use an IP cam with my DVR or even HDcctv? i dont use it on a network. im not sure if its a hybrid,

Can i just connect a HDcctv and have 1080p HD record quality or am i being silly and it will only record at a lower rate of D1? i was under the impression D1 was the best lol

joining a forum late really hits you in the face!

 

I have a HD series so i assume it would record at 1080p or is that just the monitor?

 

I have had a little look at HDcctv 1080p, can i record this with mine?

 

I have this DVR:

 

Edit

 

Thanks

Thats not a hybrid nor NVR so cant run IP cams on it

HDSD again wont run on it

the 1080P is live view only

 

As Tom says try another cable, piece cat5 and baluns

 

Also you said the picture started out ok, have you cleaned the camera since installation? has it got IR on it? could be spider webs on it etc

[Bullseye 0]

Oh well a couple of years and i may get me a HDSD

 

They made out Robox HD is casino quality but its far from it!

 

No IR and its quite new, no webs or anything

 

Its strange sometimes its OK recording but thats all it is 'OK' and other times its just not acceptable

 

i have noticed aspec in dark the live feed picture isnt as good as the recorded? still poor recorded

 

sometimes its grainy other times you can see small dot movement, I cant get good face detail unless up real close, its a 3.6mm and just a metre away unless i know the face its no good

 

sometimes for instance the dark outline of a car etc isnt of fine quality, not straight but the focus is all correct

 

I just made an order of two china (i know bad choice) 700tvl WDR sony effio E and im going to order some RG59, i think its simpler than cat5? aspec as i cant use IP anyways

 

Do any of you know where i can get a BNC compression tool in the UK? i cant find one anywhere!!!

 

All in all im abit fussy and im not very happy with my picture quality but i guess what im after i need IP or in my case i would prefer HDSD

 

I hope the new cable will fix the problem, i know the cams are basic but i have 5 more to buy so i will be spending my money there or is it not worth it? how much better picture quality could i get from a higher priced cam compared to china sony effio E? they do have quite a good spec on paper. I will be getting a covery Pixin seawolf aswel

 

Thanks

The cat5 and baluns are for analogue connection not IP, they mean you dont require a coax stipper and crimper to do BNC's

To be honest 3.6mm is a general observation size lens, people think if you can see someone in the camera you can go all CSI and zoom in and enhance etc...yes IP or HD but analogue no

If you require quality and deffination then your going to need to fill those 8 channels Bud, buy cameras with Varifocal lens as these allow you to set the image to where you require subject to where you place them and how far away, if its distance then look for 9-22mm or 5-50mm lens camera

BNC crimp kit is what you need if you want to use RG59 instead of the CAT5 / balun option - http://www.ebay.co.uk/itm/BNC-Crimp-Tool-Kit-/251188887776?pt=UK_Computing_NetworkingTools_Accessories_SM&hash=item3a7c0640e0

That gives you stipper and crimper, all you need is BNC's

[Bullseye 0]

I think i will go with shotgun RG59 just my opinion but looks a tad more tidy with 2 cables linked and i need to power close to the DVR, Isnt Compression BNC better than crimping? has a better seal and grip of about 60lb, so i read.

 

Compression BNC's are a tiny bit more expensive, as i say im a little fussy but have looked all over online but cant find the conpression tool in the UK, silly really as the compression BNC's are all over the place with no tool to fit them, must keep the sales down.

If i cant find any compression tools i wil go with the crimping set you suggested, thatnks for that

 

 

I will have a 2.8 at the front top to observe the area and a 3.6 for the back

I have ordered a covert cam with a big old 2.8-12 Varifocal lense attached. thanks for the info, i will see how i get on with the 2.8-12 to see what kind of distant lenses i will need for my other 5 cams, I dont have much idea on the exact sizes i need as havent seen much in action.

My only trouble is they need to be covert so big domes etc are out of question, i would love a PTZ but will give it all away.

bad choice im sure.

In the spec of this cam i notice NTSC is greater than PAL:

 

Specifications:

 

Image Sensor: 1/3'' SONY Effio-E DSP CCD

 

Pixel : PAL:976 (H)× 494(V) NTSC :976 (H) ×582 (V)

 

I thought PAL wasa better, am i better off using NTSC setting on the DVR due to the fact the pxel is greater?

 

Sorry for all the silly questions i really am new to all this, not as simple as i thought

 

Thanks

[tomcctv 190]

Hi. PAL is uk format. So stick with

Pal. Also the camera you are buying from china is cheaper if you buy in the uk........ We're are you based in the uk........if your not far from me you can loan crips if it helps.

[Bullseye 0]

Thanks for the offer matey but really looking for a compression tool, you have one of them?

 

I know i didnt get a very good deal and i paid extra for fast shipping so didnt do myself any favours and im sure there going to be rubbish, there was another from china same shell etc £23 but the Pal pixel was lower so i paid extra, i shop around online but couldnt find any to be honest at that price in the Uk

 

my other cam is similar and i paid £34 delivered in the UK but he sold out and it was a special price from him (normaly £50),

Can you point me in the direction as to where i can find these cams cheaper?

 

Although even better if you could point me in the direction of the best cams like these, i need them to be small, i can fit the pinhole cams in the walls etc,

 

Many thanks
